Confundí
Confundí is the first-person singular preterite (pretérito simple) form of the Spanish verb confundir. It expresses a completed action in the past in which the subject mixed up, mistook, or confused something or someone. The verb confundir comes from Latin confundere, formed by con- "together" and fundere "to pour," a lineage that contributed to senses related to blending or puzzling.
Confundí can take a direct object to show what was mixed up or mistaken: Confundí las palabras
The full conjugation in the preterite is: yo confundí, tú confundiste, él/ella confundió, nosotros confundimos, vosotros
